Creating 15-Second Mobile Game Ads for TikTok with Invideo

A 2025 guide on how to use Invideo to create dynamic, 15-second, vertical-format ads for a mobile game, perfectly optimized for TikTok.

Why This Use Case Matters in 2025

Marketing a mobile game on TikTok requires a specific type of ad: extremely fast (under 15 seconds), vertical (9:16 aspect ratio), high-energy, and visually chaotic to stop the scroll. Creating these "scroll-stopping" ads traditionally requires a deep understanding of the platform's trends and a skilled video editor. As of late 2025, Invideo can generate these ads from a single prompt, handling the formatting, pacing, and visuals automatically.

How Invideo Simplifies TikTok Ad Creation

Invideo's platform is designed for social media, with built-in understanding of platform-specific styles like TikTok.

Automated Generation (Text-to-Video)

You provide a prompt specifying the platform ("TikTok"), the length ("15 seconds"), and the game's details. The AI generates a script, generates all visuals, and assembles a video that is natively formatted for the platform.

AI-Generated & Uploaded Visuals

This is the key workflow. You can upload screen recordings of your actual gameplay. The AI will then generate new, original video clips to supplement it, such as:

  • High-energy, abstract motion graphics and "gamer" style effects (fire, lightning).
  • "UGC-style" clips of AI avatars (e.g., "an excited gamer yelling 'No way!'").
  • Dynamic, fast-paced text animations.

AI Scripting and "High-Energy" Voiceovers

The AI will generate a very short, punchy script designed to hook a viewer. You can choose from "high-energy," "intense," or "announcer" style AI voiceovers to create the right level of hype.

Intuitive Refinement (Text-Based Editing)

After the first draft, you can use simple text commands to optimize for TikTok: "Make the cuts even faster," "Add a text overlay: 'Level 100 Boss Battle'," or "Change the music to a 'trending phonk track.'"

Step-by-Step Workflow

Step 1: Upload Media & Write the Prompt

Upload a 10-second screen recording of your game's most exciting moment.

  • Example Prompt: "Create a 15-second TikTok ad for my mobile game 'CyberRun.' I am uploading a gameplay clip. The tone must be fast-paced, intense, and loud. Generate exciting graphics and a 'gamer' style AI avatar reacting to the gameplay. Use a driving, heavy electronic music track and an energetic voiceover. End with a text overlay: 'Download Now!'"

Step 2: Generate the First Draft

Invideo will analyze your gameplay, chop it up with fast cuts, generate the AI gamer's reaction, add the voiceover and music, and format the entire ad for TikTok (9:16).

Step 3: Refine with Text Commands

Use simple text commands to make it more "native" to TikTok.

  • "Make the text 'Download Now!' bigger and make it flash."
  • "Add a 'glitch' effect between the scenes."
  • "Add an AI-generated clip of a 'gold coin explosion.'"
  • "Make the voiceover sound more excited, like he's shouting."

Comparison: Traditional Workflow vs. Invideo

| Factor | Traditional Method | Invideo (2025) |

| :--- | :--- | :--- |

| Timeline | 1-2 days (capturing footage, editing, adding effects, formatting) | 5-10 minutes (generation and refinement) |

| Cost | High (video editor, motion graphics artist) | Low (fixed subscription cost) |

| Skill Requirement | Professional (TikTok-native editor) | Accessible for any developer or marketer (prompt-based) |

| Revisions | Time-consuming; a new trend requires a new edit | Instant and text-based; create 10 variations in 20 minutes |

Expert Tips for Better Results

  • Upload Your Gameplay: The ad must show your game. Upload your most visually impressive screen recordings. The AI will do the rest.
  • Specify "TikTok" in the Prompt: Mentioning the platform by name tells the AI to use a 9:16 aspect ratio, fast pacing, and platform-native text styles.
  • Keep it Under 15 Seconds: Your prompt should specify the length. For TikTok, 15 seconds is ideal, but 10 or even 8 seconds can be more effective.
  • Use "Hype" Keywords: Use prompts with words like "fast-paced," "intense," "epic," "chaos," "explosions," and "addictive" to get the right visual style.
